871,042, filed Nov. 9, 1914 and patented Aug. 6 26 1919, Patent No. 1,314,487.

This invention relates to internal combustion engines and more particularly to the general engine structure.

It has for its objects to provide an im- 10 proved, durable and eiiicient engine; in an improved method of water jacketing all operatin parts; and in particular Ian improve method of enclosing and housing all moving p arts and especially all electrical generating and distributing apparatus and connections as well' as other adjuncts, thereby excluding all foreign matter from their -working parts or which might in any way interfere with their proper operation.

With these objects in view, the invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said objects and certain other objects which will hereinafter 25 appear are attained, the invention being more particularly polnted out in the claims.

v Like parts are identified by the same reference characters in both views.

In the drawing accompanying and forming a part of this specification, Figure l is a side elevation, partly in section as follows: at A and A as online A in Fig. 2; at B as on line B -of Fig. 2; at C as on line C of Fig. 2 and at E as on line E of Fig. 2. Fig. 2 is a sectional elevation on line H-H of Fig. 1: showing the valve mechanism and enclosed water ypump andmagneto on one side and the carburetor and exhaust pipe K on the other. .f 40 In the figures, lis the engine crankcase and havin supporting arms 2, 2 etc. for supporting t e engine; 3 is the crankshaft,l

showing. one'end journal 3 and its bearing cap 4. 12 `is the center bearing cap. 60 is the connecting rod and 18 the piston. l

On the crankshaft 3 midway between the four cylinders shown is mounted a spiral gear 5 which meshes with and drives the gear 6 fastened on the lower end of vertical shaft 47 Spiral gear 56 on shaft for drivstruction.

ing magneto 39 and water pump 42, meshes with and is driven by a spiral gear (not shown) on vertical shaft 47. 'lhe valve shaft 35, which is in the nature of a small crank shaft, is driven by the spiral gear 52 mounted at its center and which is 1n turn driven by a spiral gear (not shown) on the upper end of vertical shaft, 47.

57 is a cover for the spiral gears which drive the magneto 39 and water pump 42, and one of which gears is shown at 56. 34 is a cover for the valve shaft 35 and its connections. 43 is a cover for the distributor 44 which is mounted on the end of valve shaft 35 and also for connecting wires 45 to the spark. plugs 36, 36 etc. 48 is a main cover for the pump 42, magneto 39 and wires 46 to the wire carrier 38 and thence to the spark plugs 37, 37 etc. 50 is one of the hand nuts for fastening the cover 48 to the engine. 49 is a handle for liftingcover 48. r

This covering of magneto and wiring is for the purpose of protecting them from all dust and dirt and also moisture which is liable to short circuit any electrical apparatus which is not properly protected. This is also illustrative of the use of the invention to the protecting of all other electrical or other apparatus, as generator, pump etc. which may be inuse on the engine.

58 "is the water inlet for pump 42 and 40 the outlet and 41 the water manifold to the cylinders. 25 is the cylinder water outlet manifold. 13 -is the cylinder wall; 14 the water jacket space which extends around'the valve mechanism as Well as to the bottom of the cylinders making them completely water jacketed; and 15 is the water jacket wall.

21 is the cylinders of a four cylinder engine cast en bloc, as a convenient means of construction, thoughvthe head can be cast separate as inthe usual construction, 1 for cleaning the top of the pistons though they can be as easily removed from below and the necessity'for removing the head to take out and `clean Valves does not exist in my con- My valves are easily removed from the top and carbon does not interfere with their operation as with the poppet 'y Valve.

'supply from the crank case and through the bearings which helps to cool the bearings and heat the air intake. A screen (not shown) is in this air intake near its connectIon to the crank case. 19 is one of two `branchesfrom the carburetor 17 which carries a fuel charge to cylinders Nos. 1 and 2 by means of'a passage 53 between cylinders l and 2 and to the chambers 28, 28, surround.- ing the valve mechanism of the two cylinders. A similar branch 19 (not shown) from the carburetor to a passage 53 carries the fuel to the cylinders 3 and 4 in like manner. 27 isan exhaust ipe connecting with each of the four cylin ers.

24 is a sleeve valve having ports 26 for inlet and exhaust to register with valve pocket 23. 54 is a piston valve in the sleeve valve 24. 55 is a bushing on the crank end of sleeve valve 24 to control its fuel intake ports from the carburetor. 30 and 31 are connectin rods between the sleeve valve 24 and the. va ve shaft 35 and the piston valve 54 and the valve shaft 35 respectively. 29 is the sleeve pin for connecting rod 30, and 32 is the crank pin of sleeve 24. 33 is crank pin of piston 54.

7 is the engine oil pan. 9 is an oil pump for circulating the oil in any approved manner to al l of the bearing surfaces as required and from which the oil is returned to be strained and again circulated. 8 is the oil pump shaft inserted into the lower end of vertical shaft 47 and driven by the latter. 10 is a float in housing 59 and on an oil gau which extendsv up into the housing 16 to s ow the oil level in the oil well 11.

The pad 20 on front of cylinder is for supporting a fan which can be driven by a belt which runs throu h the slot 51. l
